most is usually called either impact, indent, pin, or peen marking.
I've seen machines that claim as small as .015" character size -
LM-4400 - which is small enough for me.
YAG lasers are the perfect solution, but they're far too expensive for
me to even consider. It's like pulling teeth to get information out of
most of the marker manufacturers, but Kwikmark advertises their units
for $5,500 with no frills - - and I get the
general impression that most machines on the market are in the $10,000
range, which is much more reasonable than a laser.
I've probably sent emails to 10 or 15 different companies requesting
information on their products, and so far I've only gotten 2 brochures
in the mail, which contain LESS information than the websites, and
don't even include pricing information.
So, now that you know what I've done so far, I'll tell you what
exactly it is I'm trying to do:
Norsam Technologies makes something they call a Rosetta Disk, which is
used to store information for thousands of years -
- 3 times I attempted to order
some disks from Norsam, but they ignored my emails, just like everyone
else. Since I'm really more interested in just including an
indestructible instruction manual with a machine (or something like
that, it's not important), I don't need the vast amount of storage
that Norsam provides.
Instead, I'd rather use a 4 inch long, 1 inch diameter polished nickel
rod and wrap the information around it in a spiral. I'm going to
include a small logo as well. The information on each unit will be
unique, except for the logo. I know pin marking doesn't produce
beautiful marks when examined closely, but the finished product should
be nice-looking when taken as a whole. I think the quality of the
marker will determine how consistent the dot placement is (straight
lines versus crooked or wavy lines).
I'm only going to need around 5 units at first, so I'd rather hire a
marking shop to do it for me until my needs increase. On the other
hand, if you want something done right, you do it yourself....I'm
keeping an open mind.
So basically, I'm sold on the pin marking technique because of it's
low cost and decent results. What I'd like to know is, what's the best
marker out there? Technifor seems to be the 800 pound gorilla, though
there's lots of smaller companies out there too. I may decide to do
the logo with some kind of etching technology...does anyone know of
any other ways to get lots of physically durable text into a very
small space? Remember the information changes a lot, so investing in
etching masks may not be the best way to go. How well does etching
work with nickel? Any other suggestions are welcome.
